To all whom it may concern Be it known that l, SiLAs A. S'riiicxLAND, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Pumps for Motor-Vehicles, of whichthe following is a specification, reference being had therein tcth'e" acnipanying drawings.

It is common practice in motor vehicle construction to 'embody therein an air pump to be driven by the vehicle motor for infiating tires and other purposes, the pump being a permanent part of the structure, but in such constructions provision must-be made for the pump when a car is built, thus increasing the cost, and space which might be utilized for other purposes is taken up. An air pump which may be carried inthe tool box and quickly attached to' the motor to be positively driven thereby and which may be readily applied to any of the several motor car constructions so that it'may be sold as an accessory, is very desirable.

Modern motor vehicles which are equipped with engine starters are usually provided with a forwardly extended crank shaft to which a starting crank may be applied and it is the object of this invention to provide means whereby a suitable pump may be detachably supported with its crank shaft in axial alinement with the projecting end of the motor shaft; and to prov'ide a suitable connection for detachably engaging the crank shaft of the motor to drive the pump directly from the engine without the necessity for intermediate gears or other spee reducing means, said support and connection being so constructed and arranged as to adapt the same for connecting the pump with any one of the several types of construction used by motor car builders.

A. further object of the invention is `to provide means whereby the clutch member commonly employed to connect the starting crank with the engine shaft may. be utilize to connect the air pump with said shaft; and to provide certain other new and useful fea tures in the construction and arrangement of parts.

To these ends the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawings in which- Figure 1 is a sectional view of the ford tor vehicle. j

ward end of a motor car showing an air pump construction embodying the invention in place thereon; Fig. 2 'is an enlarged detail of the air pump showing the same in transverse vertical section; Fig. 3 is a similar detail showing the air pump and conn ecting means therefor in longitudinal vertical section; Fig. 4 is a detail similar to Fig. .3 showing the air pump in side elevation and illustrating a modification ofthe invention to adapt it for use upon a different motor car construction; and Fig. 5 is a similar detail showing a further modified construction.

In Figs. 1 to 3 inclusive a motor car construction is shown in. which the crank shaft of an internal combustion engine 1 has a forwardly projecting end 2 provided with a pin 3 for the engagement therewith suitable crank not shown) for turning the lcrank shaft to start the engine. A channel iron frame member 4 extends across the forward end of the vehiclev frame beneath a radiator 5 and is provided with a tubular member 6 directly opposite the projecting end 2 of the crank shaft, adapted to form a guide bearing for the starting crank when the same is engaged with the crank shaft to start the motor. This construction is illustrative of one of a number of motor car constructions commonly used where an automatic starter is provided for cranking the internal combustion engine. Other constructions in common use are illustrated in Figs. 4 and 5 but I do not wish to limit myself to any particular form or construction of mo- While l have illustrated a particular form of air pump which l believe to be suitable for the purpose, l do not limit myself to any particular construction of pump as any suitable pump having a crank shaft 7 for actuating its pumping device or devices, such as a piston 8, may be employed. ln the construction of air pump shown,

having ports 10 for the admission of air thereto and an exhaust port 11 controlled by a check valve 12 leading to a passage 13 through a nipple 14 to which a suitable air hose 15 may be securedfor conducting the air to the valve of a pneumatic tire or other receiving chamber or device.

The crank case of the pump is preferably provided with an extended hub 16 which forms a bearing for the shaft 7 exof athe piston 8v d Yis reciprocable within a vertical cylinder 9 ice lll@

l therewith, and to tending therethrough and also forms Va sup' port for the pump when said hub is inserted within the forward end of the tubular bearing 6, as illustrated in Fig. 3. In order to connect the rear end of the pump crank shaft 7 with the forward end 2 of the engine shaft in the particular ltype of vehicle construction shown in Figs. 1 and 3, a tubular connecting member 1'7is secured in any suitable manner, as by a pin'18, with the reduced rear end 19 of the shaft 7. The rear end o'f this tubular member or sleeve 17 is formed with an inwardly extending longitudinal slot 20 having a laterally extended andfcurved inner forward end and this slot is adapted to receive the pin 3 todetachably connect the pump with the motor.

The curved inner end of the slot 20 is so arranged that when the motor is started,- the pin will move into the lateral end of the slot, and thus lock the sleeve in engagement prevent the pump casing and its cylinder 9 from rotating when the engine isv started, suitable means, such as a bracket 21 having a lug' 22 to lengage beneath the cross member 4, is p rovided upon the crank case of the pump, said'bracket being preferably made detachable so that lwhen the pump is used upon other vehicles having a different construction, this bracket may be dispensed with. l

In the vehicle construction shownin Fig. 4, the forward end 2 of the motor crank shaft is shown as provided with a clutch member 23 having suitable teeth or projections to engage like projections upon a clutch member 24 carried by an extension 25 of the crank shaft. The clutch jaws are normally held out of engagement by means of a spring 26 and the forwardend of the extension shaft 25 projects through a tubular bearing 27 upon a frame member 28 extending across beneath the radiator 5. rIhe tubular bearing member 27 is provided with an `outwardly extending pin 29 shown in dotted lines, and the air pump is supported by this bearing member 27- when inl operative position, by a sleeve 30 which is secured in any suitable manner 31 to the rear end of the hub 16 on the pump casing. The sleeve 30 is formed wlth a longitudinal slot similar to the slot 20 to engage the pin 29. rIhe forward end of the extension shaft 25 is preferably reduced in' diameter to engage a socket provided therefor in the end of the crank shaft 7 of the pump and-a key 32 or other suitable means is provided to cause said extension shaft and pump shaft to turn together.

In order to hold the clutch jaws 23 and 24 in engagement so that they will transmit motion and turn the extension shaft 25 to drive the pump, the'sleeve 30 is formed to engage the in 29 and this engagement is accomplished) by pushing the sleeve endwise as by pinsl upon the bearing member 27 against the action of the spring 26 which tends to hold the shaft extension 25 projected, and when the pin 29 has entered the vslot the pump casingand sleeve are turned to bring the pin into thelaterally extended end of the slot and thus lock' the sleeve in place with the clutch members engaged.

In Fig. 5 a vehicle construction similar to that shown in Fig. 4 is illustrated but in this instance the frame members 4 and 28 are dispensed with and the extension shaft 25 is supported in an elongated bearing 33 on the casing of the engine. The pump is supported as in Fig.l 4 by an elongatedA sleeve 34 secured at its forward end tothe hub 16 of the pump and provided at itsrear end with the slot 20 to engage a pin 29 on the extended bearing 33 which is turned down to slip into the end .of the sleeve. The extension shaft 25 has one or more pins 35 on its rear endto engage corresponding notches in the tubular extended end 36 of the engine crank shaft, and the extension shaft is normally held with the pin out of engagement with the notch, by means' of a spring 37 sleeved thereon between a collar 38 on the shaft and the outer end of the bearing 33. The pump casing isV thus firmly supported and'locked in position bythe sleeve 34 which also serves to hold the clutch members comprising the pins 35 and their slots, in engage ment.

Cbviously, changes may be made to adapt the device to be applied to. other motor vehicle constructions and I do not therefore limit myself to the particular constructions or arrangements shown.
